Performing on the edge of the street in America! (6)
I believe the answer is:
busker
'performing on the edge of' is the definition.
The definition suggests a singular noun which matches the answer.
'street in america' is the wordplay.
I cannot quite understand how this works, but
'america' could be 'us' (United States) and 'us' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'the' is the link.
Can you help me to learn more?
(Other definitions for busker that I've seen before include "player in street" , "Street performer" , "Street entertainer" , "Public entertainer" , "Street musician" .)
